2. Description of the Related Art The prior art is known in the art, US PATE.
As shown in NT No. 5151789, by incorporating an infrared remote control signal converter and a converted infrared signal (hereinafter referred to as a converted IR signal) transmitter in a video, operations such as video recording and a cable box which is an external device can be realized. There is a system in which a channel switching operation can be performed only by a video remote controller which is an infrared remote control device capable of transmitting an IR signal. As an existing system, there is a configuration as shown in FIG. 5, assuming that a cable box is placed on top of a video. Here, 1 is a video remote controller, 2 is a video having an infrared signal conversion function, 3 is a cable box, 4 is an IR signal from the remote controller, 5 is a converted IR signal from the cable box, and 6 is an IR signal receiver inside the video. , 7 is a converted IR signal transmitter inside the video, 8 is a converted IR signal receiver inside the cable box, 10 is the wall of the room, 11 is an IR signal transmitter inside the remote control, 12 to 15
Is the window of each transmitter and receiver. In this example, the converted IR signal 5 is transmitted from the front side of the video 2 and the front side of the upper surface.

[0003]

In the prior art of FIG. 5, the converted IR signal 5 from the front side uses the reflection of the wall 10 or the like, and there is no reflector or the reflector is far, etc. The cable box 3 However, there is a problem that the converted IR signal 5 does not reach and malfunctions. Further, regarding the converted IR signal 5 from the front side of the upper surface, it is expected to be in the wide-angle range of the converted IR signal 5 and the wide-angle range of the converted IR signal receiving section 8 of the cable box, and when the respective wide-angle ranges do not overlap, the same cable box 3 is used. However, there is a problem that the converted IR signal 5 does not reach and malfunctions. Furthermore, there is a problem that the IR signal 4 transmitted from the remote controller 1 of the video 2 is directly received by the cable box 3 and malfunctions.

Therefore, it is necessary to prevent these malfunctions.

[0005]

In order to solve the above-mentioned problems, a shielding plate that can be housed inside the device is provided on the upper surface of a video which is an infrared remote control signal conversion device of an infrared remote control system to surely shield disturbance. A conversion IR signal transmitter that can be adjusted and moved is provided on the back side of the shield plate to reliably transmit to any external device with various receiver positions.

[0006]

By this method, it is possible to construct an infrared remote control system including an infrared remote control signal conversion device which has few malfunctions, has a flat upper surface and does not spoil the appearance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1, 2, 3, 4, and 5. FIG. 1 is an explanatory diagram of an embodiment showing the present invention, FIG. 2 is a block diagram of the entire system, FIG. 3 is an explanatory diagram of a conversion IR signal transmitter, and FIG.
[FIG. 3] is an explanatory view of a shield plate representing the present invention.

As shown in FIG. 2, when the IR signal 4 is input from the video remote controller 1 to the IR signal receiver 6 as shown in FIG. 2, when this input is a control command to the cable box 3, a signal conversion function is provided. The microcomputer 9 has an IR signal 4
To a signal for the cable box 3, and the converted IR signal transmitter 7 outputs the converted IR signal 5 toward the converted IR signal receiver 8 inside the cable box 3 to connect the cable box 3 and the video 2 to the remote control of the video 2. It is a system that can be controlled by only one.

As shown in FIG. 3, the conversion IR inside the video
The signal transmitter 7 is composed of an infrared LED 7a and a housing 7b, and a lead terminal 17 formed of a spring material is fixed to the terminal portion of the infrared LED 7a. Further, as shown in FIG. 4, the converted IR signal transmitter 7 is attached to the shield door 16 so as to be held by a guide portion 16b formed in the longitudinal direction. The shield door 16 has a metal rail 18
Is provided in the longitudinal direction, and the rail is connected to the signal converter inside the video by a raid line. The lead terminal 17 is constantly urged by the spring 18 against the rail 18 and is in contact therewith. With the above structure, the converted IR signal transmitter 7 can be moved and adjusted to any position in the longitudinal direction of the shield door 16.

The shield door 16 is pivotally supported on the front side of the upper surface of the video 2 by the left and right shaft portions 16a and can be opened and closed as shown in FIG. This allows the cable box 3
When not using, the top surface of the video 2 can be flattened by closing the shielding door 16 so that the video 2
It does not spoil the aesthetics of.

If the cable box 3 is used by being superposed on the video 2, the IR signal of the remote controller 1 is surely prevented from entering the converted IR signal receiver 8 inside the cable box 3 by the shield door 16 and the converted IR signal is received. The position of the container 8 ensures that the converted IR signal 5 can be transmitted to any cable box 3 of any variety.

[0012]

According to the present invention, by providing a shield plate which can be housed inside the device on the upper surface of the video and a converted IR signal transmitter which can be adjusted and moved on the back side of the shield plate, malfunctions can be reduced.
It is possible to configure an infrared remote control system including an infrared remote control signal conversion device which has a flat upper surface and does not spoil the appearance.
